Could you tell me if the supercoup NR1 nibbler shears can cut through 1/16 steel, and will it be able to cut about 1/8 inch off of an edge? I am replacing some rear windows that were an add on to my panel van, and need to enlarge them a small amount. Since this is a small project I thought this nibbler would be a cheap option, but only if it will take sheet metal off an edge. Thanks, Tom
